The Bracelets Came With Pyrotechnics Inside
Each time the superheroine has to block a bullet, they had to use special effects to bring it to life. Mind you, the show was made before CGI became commonplace. The executives had to rely on technical wizardry to bring the effects to life. There were stars on the bracelets that were actually small pyrotechnics with attached wires. When they needed the sparks to fly, she just had to press a button!
It Was Not Easy To Pull This Off
This method was not flawless, of course. For one thing, it was a little tricky to keep the remote control hidden. The most observant fans of the show might have noticed that there was something hidden away in the palm of the actress. The effect looked great, but you can just imagine how risky it was to do this.
